Correction to: Nature Reviews Molecular Cell Biology https://doi.org/10.1038/s41580-019-0168-5, published online 13 September 2019.

In the version of this article initially published, there were errors in the pseudouridine (Ψ) structure displayed in the lower-right side of the Box 1 figure, including an extra N denoting a N–C glycosyl bond appearing below HN, and a single instead of a double bond appearing at the top O in the figure. A corrected structure now appears in the revised box figure, shown as Figure 1 below.
